Ceramic PCB and Substrate: Alumina PCB, Aluminum Nitride Base, Copper Clad

Ceramic PCB (ceramic substrate) refers to a special process board in which a copper foil is directly bonded to a surface of an alumina (Al2O3 ) or aluminum nitride (AlN) ceramic substrate (single or double-sided or multilayer Ceramic PCB) at a high temperature. The ultra-thin composite substrate produced has excellent electrical insulation properties, high thermal conductivity, excellent solderability, and high adhesion strength, and can etch various patterns like a PCB board, and has a large current carrying current ability.

Ceramic PCB Classification

1. According to the material Alumina (Al2O3) Ceramic PCB Beryllium Oxide (BeO) Ceramic PCB Aluminum Nitride (ALN) Ceramic PCB

2. According to the manufacturing process HTCC (High-Temperature Co-fired Ceramic) LTCC (Low-Temperature Co-fired Ceramic) DBC (Direct Bonded Copper) DPC (Direct Plate Copper) Ceramic PCB is a thermal conductive organic ceramic circuit board with high thermal conductivity and prepared at a temperature below 250°C using thermally conductive ceramic powder and organic adhesive, ceramic PCB types by material including alumina pcb, Aluminum nitride ceramic PCB, Copper clad ceramic PCB, Zirconia ceramic base PCB.

Four types: HTCC, LTCC, DBC, and DPC

1. The HTCC (high temperature co-fired) preparation method requires a temperature above 1300°C, but due to the choice of the electrode, the preparation cost is quite expensive.

2. The LTCC (low temperature co-firing) requires a calcination process of about 850°C, but circuit precision is poor, and the thermal conductivity is low.

3. The DBC requires formingan alloy between the copper foil and the ceramic, and the calcination temperature needs to be strictly controlled within the temperature range of 1065-1085°C. Because the DBC requires the thickness of the copper foil, generally, it cannot be less than 150-300 microns. Therefore, the wire width to depth ratio of such ceramic circuit boards is limited.

4. The preparation methods of DPC include vacuum coating, wet coating, exposure and development, etching, and other process links, so the price of its products is relatively high. In addition, in terms of shape processing, DPC 1800 ceramic fiber board plates need to be laser cut. Traditional drilling and milling machines and punching machines cannot accurately process them, so the bonding force and line width are more precise.
